Heating in Grand Rapids, MI
Manufactured home furnace repair around Grand Rapids
Manufactured homes use their own kind of furnace, sealed-combustion downflow units built for the home, and their own duct layout. We work on both.
The short answer
Manufactured home furnace service near Grand Rapids covers the sealed-combustion downflow furnaces built for manufactured homes, which draw combustion air from outside and blow warm air down into ducts under the floor. We repair igniters, blowers and controls, replace furnaces with approved manufactured home models, and fix crossover and belly ducts that leak heat under the home.

Different from a house furnace
Why manufactured homes need the right furnace
A manufactured home furnace sits in a closet, pulls its combustion air from outside through a roof jack and pushes heat down into a duct that runs under the floor. Replacements must be models approved for manufactured homes, not standard house furnaces, and the venting and roof jack have to match.
Central air is often added to the same furnace; see our AC repair page. Homes on propane are covered on gas line installation work when a new connection is needed.
What we fix
Downflow furnace repair
Most no-heat calls on manufactured home furnaces come down to a failed igniter, a dirty flame sensor, a pressure or limit switch, a blower motor or a control board. Because these furnaces sit in a tight closet, a clogged filter or a blocked return grille in the closet door overheats them quickly and trips the limit. We test the full sequence, clean the burners and flame sensor, check the combustion air intake and roof jack, and replace the part that failed.
Manufactured home furnace replacement
When a furnace is past repair, it has to be replaced with a model approved for manufactured homes, matched to the existing floor opening, the duct connection and the venting through the roof. We size it for the home, set it on the existing base, connect gas or propane and the roof jack, and test combustion before we leave. Many owners add or replace central air at the same time, since the coil sits on the same furnace and both can be matched and installed in a single visit.
Crossover duct and belly duct repair
Heat travels under a manufactured home through a main duct in the belly, and in double-wide homes through a flexible crossover duct between the two halves. Crossover ducts sag, tear or come loose, and belly ducts open up at seams, so the furnace runs hard while the rooms stay cold and the heat warms the crawl space instead. We reconnect, seal or replace crossover ducts and patch the belly so the air reaches the rooms. Sealing the belly also keeps rodents and cold air out of the floor.
